“…The effectiveness of the proposed PPSAB method has been analyzed using the NS2 platform and its simulation setup is specified in Table 2. The performance results of the proposed PPSAB method are compared with the results obtained from existing methods like HTCP, 19 CCPR, 25 MC, 27 and MCU 28 . These methods can be evaluated through various performance metrics such as normalized overhead (NO), end to end delay (EED), packet delivery ratio (PDR), average energy consumption (AEC), and network throughput (NT).…”

In today's world, a mobile ad hoc network plays a predominant role for numerous applications such as education, entertainment, emergency services, tactical services, and home applications. The performance of IEEE 802.11 based wireless ad hoc networks degrades due to high contention for the shared medium among multiple ad hoc nodes.However, the shared medium can be accessed by multiple nodes, which causes link collisions and packet drop at the link level. These kinds of packet drops have a direct impact on the overall performance of the transmission control protocol (TCP). In this article, a new robust prioritized packet scheduling with adaptive backoff window (PPSAB) mechanism has been proposed to enhance the quality of service of TCP in the wireless scenario. In order to determine the congestion in the network, the proposed PPSAB mechanism anticipates the cross-layer parameters instead of transport layer parameters. The proposed access scheme assures minimized collisions and energy by setting the node level access to prevailing network parameters. The performance of the proposed PPSAB has been evaluated using an NS-2 environment and the results manifest that the normalized overhead is reduced by 20% and network throughput is increased by 17% than the existing methods. K E Y W O R D Senergy consumption, mobile ad hoc network, prioritized packet scheduling, quality of service INTRODUCTIONThe rapid development of wireless communication demands uninterrupted network connectivity among the communicating. Typically, mobile ad hoc network (MANET) is the collection of self-organizing and self-configuring mobile nodes which is not dependent on any stable and central coordinating infrastructure. The mobility of the nodes makes the topology of the network changes dynamically and the nodes may join and leave the network at any instance. 1 IEEE 802.11 ascertains single-hop reliability at medium access control (MAC) layer in MANETs.Two types of medium access techniques are generally utilized in IEEE 802.11. The first method, the distributed coordinated function enables the data flow among communicating devices while requiring no control infrastructure. Second, point coordinated function in which a central coordinator controls access to the shared wireless channel. 2,3 The basic channel access method exploited in distributed coordinated function is carrier sense multiple access collision and avoidance by the nodes. Every time, the shared channel is sensed by the node before data transmission and the node can transmit data if the medium is free or defer transmission until the medium becomes free.

“…Transmission Control Protocol over Internet Protocol(TCP/IP) protocol suite consists of four layers such as the application layer, transport layer, network layer, and data lin layer. The topmost application layer manages the applications, transport layer responsible for transferring reliably or unreliable data segments of related application-specific processes, network layer deals with data packets and IP addresses and data link layer deals with data frames based on Media Access Control (MAC) address [12]. In MANETs, mobile nodes do not only forward data packets but also support effective and strong routing functioning.…”

Mobile Ad-hoc Network (MANET) is a network of heterogeneous and homogeneous wireless mobile nodes to offer provisionally communication facilities to users for the exchange of data packets without having the well-established infrastructure in a limited geographical area. Resourceconstrained mobile nodes are not a permanent part of the network instead mobile nodes are individualistically can join or leave the network at any time. Network topology, connectivity of nodes and routing information change dynamically based on multi-hop routing. The main focus of this research work is to evaluate the performance of DSR, TORA reactive routing protocols and OLSR proactive routing protocol of MANET under augmentation of Nodes Density investigation based on Random Way Point (RWP) mobility model. DSR, TORA, and OLSR protocols are simulated by using OPNET modeler 14.5 by creating three different scenarios. These protocols are compared and analyzed with respect to Wireless LAN delay, Wireless LAN throughput, Wireless LAN network load, Routing traffic send and Routing traffic received.

“…68 • Packet loss: The packet loss happens when the packet does not reach its destination and denotes the ratio of lost packets overall the transmitted packets. 69,70 • Scalability: The VANETs could be a large-scale network. The data collection mechanisms should consider the operation of many unicast routing requests simultaneously.…”

Recently, the fast growth of communication technology has led to the design and implementation of different types of networks in different environments. One of these remarkable networks is vehicular ad hoc network (VANET).The ubiquitous connectivity among vehicles is possible through VANET in the absence of fixed infrastructure. Moreover, it provides safety and comfort to people sitting in the vehicles. In this regard, collecting information from vehicles that are moved constantly is an essential challenge. To develop an efficient method for data collection in the VANET, some parameters must be considered such as data aggregation, latency, packet delivery ratio, packet loss, scalability, security, transmission overhead, and vehicle density. Since data collection has a significant importance in the VANET, the aim of this study is to investigate the existing methods and describe the types of important issues and challenging problems that can be addressed in data collection in the VANET. The data collection techniques are investigated in four primary groups, namely, topology-based, cluster-based, geocast-based, and fog-based.Also, the mentioned parameters are important to compare all of the presented techniques. KEYWORDS communication architecture, data collection, VANET, vehicle-to-vehicle communication, vehicular ad hoc networks | INTRODUCTIONOne of the growing disruptive innovation is the Internet of things (IoT), which allows physical devices to communicate over heterogeneous networks. 1-3 Moreover, one of the IoT applications is vehicular ad hoc network (VANET), 4 which has been developed as a powerful technology aimed at providing safety and comfort to people sitting in the vehicles. 5,6 Moreover, it affords wireless communication among vehicles, and dynamic traffic data is transferred with a high accuracy and low cost. 7,8 The VANET is a module of intelligent transportation systems (ITS) and a subdivision of mobile ad hoc network (MANET). 9,10 Typically, the vehicles are armed with sensing equipment and have a high storage and processing capacity. 11 The unique features of the VANETs include higher node density, instability of wireless channel and limited bandwidth, predictability of vehicular pathway, highly dynamic network topology that change quickly and repeatedly, sufficient energy and resources, and hard delay constraints. 12-14 A large scale of VANET is foreseen to be available in the near future because of the rapid growth of vehicles equipped with communication abilities. 15 The data dissemination and the data collection of vehicles are two significant factors supported by VANET. 16
